Explanation of the parameters
Parameters
Synchronous
speed running
Synchronous speed running (SPEED (SBus)):
The speed of the inverter that is set up as the slave follows the speed of the master in-
verter. Set the speed ratio with P751 Scaling slave setpoint at the slave inverter. P324
Slip compensation 1 / P334 Slip compensation 2 of the slave is to remain at the value
set in the startup setting.
Example:
Load sharing
Load sharing (LOAD SHAR (SBus)):
This function lets two inverters control the same load. It is assumed in this case that the
shafts of the motors corresponding to the master and the slave are rigidly connected to-
gether. You are recommended to use the same motors with the same gear ratios, oth-
erwise different delays may result during starting/stopping due to the pre-magnetizing
time and the brake release/application time. Set the load load distribution ratio (recom-
mendation: 1) with P751 Scaling slave setpoint.

1 (then 1 : 1)
Set different values
P814 SBus groupaddress
Set the same value (0 ... 63)
P816 SBus baud rate
Set the same value (125, 250, 500 or 1000 kBaud)
NOTE
P324 Slip compensation 1 / P334 Slip compensation 2 of the slave must be set to 0.
Better behavior can be accomplished by setting the slave as follows:
•
•
•
Ramps P130 / P131 / P132 / P133: 0 s
•
P301 Minimum speed 1 / P311 Minimum speed 2: 0 min
